I don't think we can do a lot with Q1 without some data. Data would probably help with Q2 as well.  Have a look at the following links especially on how to use dput() to supply sample data.

> curves in parallel and doing it in R would save a long time.

> Question 2:
> The second plot (Figure 2) is a smoothed curve through time in which each
> peak indicates an independent event. I would like to know when exactly on
> time (x axis) each one of these peaks ocurred. So, how to intercept the x
> axis at the maximum value of a peak.
